Elevator car door motor, elevator car and elevator door opening and closing control method

Abstract

The invention relates to an elevator car door motor, an elevator car and an elevator door opening and closing control method. The elevator car door motor comprises a fastening device, a lock hook, a lock seat, a first driving mechanism and a second driving mechanism, Wherein the fastening device comprises a fastening base, a fastening arm and a fastening rod, the fastening rod is connected to the fastening base through the fastening arm so that the fastening rod can rotate relative to the fastening base, the lock hook is rotatably installed on the fastening base, one side of the lock hook is matched with the fastening rod in an abutting mode, the other side of the lock hook is used for being matched with the lock seat in an interlocking mode, the first driving mechanism is connected with the fastening base and used for driving the fastening device to move in the height direction of an elevator car, and the second driving mechanism is connected with the lock seat and used for driving the lock seat to move in the height direction of an elevator door. Therefore, the center height of the fastening device and the center height of a landing door lock roller coincide all the time, it is guaranteed that the vertical height of the landing door lock roller relative to the fastening device is centered when a door is opened and closed, and the using safety of an elevator is improved.

Description

Technical field [0001] Technical Field The present invention relates to an elevator, particularly to a door of the elevator car, the elevator car and the elevator door control method. Background technique [0002] In order to meet the needs of different architectural features, for example, has a sandwich construction, or there is a load beam doorway height restrictions, such as a need to configure one or more layers of a height lower than the case where other layers doorway. Different heights encountered landing, only by way of non-standard design to deal with the engaging means or method of adding high door / on the ridge, and this method will cause the door each engaging area increases, and out of the hoistway for staff a security risk. SUMMARY [0003] Based on this, it is necessary to provide an elevator car door, the elevator car and the elevator door control method, it is possible to achieve accurate open, improving the safety of the elevator used. [0004] An elevator car...

AI Technical Summary

Problems solved by technology

When encountering landings of different heights, it can only be dealt with by non-standard design fastening devices or by adding high-rise door panels / upper sills, and this method will increase the door opening and fastening area of ​​each floor, which is difficult for the staff entering and exiting the shaft. bring security risks
